VMware DRS continuously monitors utilization across resource pools and intelligently allocates available resources among the virtual machines based on pre-defined rules that reflect business needs and changing priorities. When a virtual machine experiences an increased load, VMware DRS automatically allocates additional resources by redistributing virtual machines among the physical servers within the network. VMware DRS allows IT organizations to:Prioritize resources to the highest value applications in order to align resources with business goals.Optimize hardware utilization automatically and continuously to respond to changing conditions.Provide dedicated (virtual) infrastructure to business units while giving central IT complete control over hardware.Conduct zero-downtime server maintenanceHow does VMware DRS work?VMware DRS dynamically allocates and balances computing capacity across collections of hardware resources aggregated into logical resource pools. VMware DRS continuously monitors utilization across the resource pools and intelligently allocates available resources among virtual machines.VMware DRS allows users to define the rules and policies how virtual machines share resources and how these resources are prioritized among multiple virtual machines. When a virtual machine experiences increased load, VMware DRS first evaluates its priority against the established resource allocation rules and policies, and if justified, allocates additional resource. .Additional resources are allocated to the virtual machine by either migrating it to another server with more available resources or by making more “space” for it on the same server by migrating other virtual machines to different servers..VMware DRS can be configured to operate in automatic or manual mode. In automatic mode, it migrates virtual machines to the most appropriate physical servers. The live migration of the virtual machines to the different physical server is executed completely transparent to end-users though VMware VMotion. In manual mode, VMware DRS provides a recommendation for optimal placement of virtual machines, and leaves it to the system administrator to decide whether to make the change.Flexible hierarchical organization of resource pools allows administrators to match available IT resources to the needs of the business organization. Individual business units can receive dedicated IT resources while still benefiting from the efficiency of resource pooling. Robust access privileges make it possible to delegate routine infrastructure tasks for a business unit resource pool to a business unit administrator.VMware DRS optimizes IT environments to align resources with business goals while ensuring flexibility and efficient utilization of hardware resources.How Is VMware DRS Used in the Enterprise?Align IT resources with business priorities. Define rules and policies how resources are prioritized among virtual machines. VMware DRS dynamically and intelligently allocates IT resources to the highest priority virtual machines to ensure optimal alignment between business and IT.Guarantee IT autonomy and service levels to business organizations. Provide dedicated IT infrastructure to business units while still profiting from higher hardware utilization through resource pooling.Dramatically increase system administrator productivity. Enable a single system administrator to monitor and effectively manage a large pool of infrastructure resources.Automate hardware maintenance. Place a physical server in maintenance mode and VMware DRS will automatically migrate all virtual machines to other physical servers, allowing server maintenance with zero downtime.Resource Pool

23 Nasaďte High availability s VMware HAVMware HA zajišťuje cenově velice efektivní vysokou dostupnost pro všechny aplikaceCo je to?Automatický restart virtuálních serverů v případě výpadku fyzického serveruZákaznický dopadCenově efektivní vysoká dostupnost pro všechny aplikaceNení potřeba dedikovaný stand-by hardwareŽádné náklady a složitosti spojené s clusteringemXWhat is VMware HA?VMware® High Availability (HA) provides easy to use, cost effective high availability for applications running in virtual machines. In the event of server failure, affected virtual machines are automatically restarted on other production servers with spare capacity. VMware HA allows IT organizations to:Minimize downtime and IT service disruption while eliminating the need for dedicated stand-by hardware and installation of additional software.Provide uniform high availability across the entire virtualized IT environment without the cost and complexity of failover solutions tied to either operating systems or specific applications.How Is VMware HA Used in the Enterprise?VMware HA allows companies to provide high availability to any application running in a virtual machine. With VMware HA IT organizations can:Protect applications with no other failover option. Provide cost-effective high availability for any application running in a virtual machine. High availability solutions are often relatively complex and expensive, and typically reserved for mission critical applications. VMware HA provides a cost-effective high availability solution that makes high availability possible for software applications that were formerly left unprotected.Establish consistent “first line of defense” for an entire IT environment. Unlike other high availability solutions that are operating system or software application specific, VMware HA represents a consistent, easy to manage high availability solution for the entire IT environment. VMware HA provides basic failover for any application with minimum cost and management overhead.How Does VMware HA Work?VMware HA continuously monitors all servers in a resource pool and detects server failures. An agent placed on each server maintains a “heartbeat” with the other servers in the resource pool and a loss of “heartbeat” initiates the restart process of all affected virtual machines on other servers. VMware HA ensures that sufficient resources are available in the resource pool at all times to be able to restart virtual machines on different physical servers in the event of server failure. Restart of virtual machines is made possible by the Virtual Machine File System (VMFS) clustered file system which gives multiple ESX Server instances read-write access to the same virtual machine files, concurrently. VMware HA is easily configured for a resource pool through VirtualCenter.Resource Pool

The “home directory” contains metainformation about the virtual machine i.e. configuration,swap, log files. It next “self VMotions” to the new VM homelocation. The disk movements follow after the homedirectory migration. First, Storage VMotion creates a “childdisk” for each virtual machine disk to be migrated. Once themigration operation has started, all disk writes are directedto this “child disk”. Second, the “parent”, or original, virtualdisk is then copied from the old storage device to the newstorage device. In step three, the child disk that is capturingthe write operations are then “re-parented” to the newlycopied parent disks. And, in the final step the child disk isconsolidated into the new parent disk and the ESX host isnow re-directed to the new parent disk location.The switchover process of home directory and diskmigration, creation of child disks and parent disks, re-parenting and consolidation of child disks happens withinsub-2 seconds, fast enough to be unnoticeable to theapplication user.
